Performance: event-driven stdout pump (no polling thread per socket, no 200ms
coalescing stall), keystrokes written immediately, blocking SSH reads, bounded
deque queue with batch drain, incremental UTF-8 decode, buffered session log,
non-blocking session teardown, shorter login/settle waits, xterm WebGL renderer
and idle-time direct writes. Zero-latency fake device: echo p50 11ms -> 2.3ms,
command RTT 219ms -> 20ms, bulk output 2.1 -> 8.3 MB/s.
Audit: track the device's own input row server-side (webcrt_cmd_audit) and
resolve each Enter from the echoed line feed, so Tab, backspace, cursor-key
edits, history recall, paste, Ctrl-C and pagers record what actually ran.
Password lines are redacted; pending Enters are flushed on close.
Hop: stop closing the hop session when the target prints the same prompt as the
hop (system-view); recognise the Huawei "closed by the remote host" message.
Generic NEs that show a network prompt now get the network key map.
Adds bench_webcrt.py, fake_ssh_device.py and e2e_webcrt_input_scenarios.py.

ZTE post-login banners can line-wrap login-failure stats and were misclassified before the target prompt was recognized.

LLDP discover and config collect were timing out on --More--; send vendor paging-off after nested/bastion auth, and attach session-log tails so failures show where the CLI stuck.

Some hops only accept stelnet in system-view; make it a saved yes/no setting (default off) instead of auto-retry, and always ALTER the new column on API boot when Alembic skips legacy DDL.

Skip Huawei special_login_handler under interactive WebCRT, harden stelnet host-key auth, and echo hop/login progress into the terminal during connect.

Keep the facade for callers, retarget unit-test patches to ne_session_connect, and fix the ConnectHandler coverage case to use a non-Cisco device type.
